No. Its not weird. i know lots of girls who are dating guys shorter than them.
Is it weird that my best friend is dating someone way shorter than her?
No, not at all. As long as she's happy, that's what really counts, don't you think? Weird? No.
It's weird that you obviously care about something as superficial as height - more than things that really matter to a relationship.
It may look weird on the outside, but how they care for one another is the issue. You shouldn't get hung up on the physical as the height is not the issue. As what's on the outside is being forced on us by the media - as in black versus white - you could make a case based on looks. However, mature people don't care what someone looks like. They care about their heart, their character, their values.
No. If women didn't date shorter guys, than Tom Cruise never would have had a date.
Weird as in "not the norm"? Then yeah, it isn't what we normally see. Weird as in "wrong"? Absolutely not. There's nothing wrong with her dating a shorter person. If they're happy, that's all that matters.
